Thyroid Gland.ppt Task:
You and your group will be responsible for putting together a defensive presentation of an endocrine gland. You and your group will be giving this presentation during class. Your presentation must include:
http://www.scottsdalethyroid.com/wst_page5.html a.k.a. the "Adams Apple" thyroxine (T4) and triiodothyronine (T3) are the hormones that are produced from the glands
T3 and T4 are then released into the blood stream and are transported throughout the body where they control metabolism (conversion of oxygen and calories to energy). Every cell in the body depends upon thyroid hormones for regulation of their metabolism.The normal thyroid gland produces about 80% T4 and about 20% T3, however, T3 possesses about four times the hormone "strength" as T4.When the level of thyroid hormones (T3 & T4) drops too low, the pituitary gland produces Thyroid Stimulating Hormone(TSH) which stimulates the thyroid gland to produce more hormones. The pituitary gland itself is regulated by another gland, known as the hypothalamus (shown in our picture in light blue). The hypothalamus is part of the brain and produces TSH Releasing Hormone (TRH) which tells the pituitary gland to stimulate the thyroid gland (release TSH). One might imagine the hypothalamus as the person who regulates the thermostat since it tells the pituitary gland at what level the thyroid should be set.
· The hormone(s) produced by your endocrine gland. · The stimulus that tells your gland to produce hormones. · The control mechanism that tells your gland to stop producing hormones. · The function(s) of the hormone(s) produced by your gland. What are the target organs/cells and how does the message carried by the hormone help maintain homeostasis. This is probably the most important part of your presentation.
